Detention and Filtration?Out of Sight, Out of Mind
Rapid growth in the Austin metropolitan area kindled regualtions to protect the environment. Rigid enforcement of function-oriented guidelines and increased emphasis on productivity has...
Systems Approach for Irrigation Management of Complex Projects Involving Large Number of Farmers Under Severely Arid Regions
An Irrigation Management Information System (IMIS) was developed for complex irrigation projects involving a large number of farms under severely arid conditions. This system is a computer...
Effective On-Farm Irrigation Scheduling in the Humid Southeast
An extension demonstration of a checkbook type irrigation scheduling system using a personal computer and spread sheet is described. The system incorporates typical crop water use curves,...
Aquatic Weed Control by Grass Carp in Cool Water
Diploid grass carp have significantly controlled problem aquatic vegetation during a 3-year study in a northern Colorado irrigation canal where water temperatures ranged from 0 to 25?C....
Drought in Tennessee: Implications on Irrigation System Capacity
Recent droughts in Tennessee have led to a study of the required irrigation system capacity for the state. Data from 1951 through 1988 were analyzed for probabilities of precipitation...
Managing a Drought Through Advance Water Resources Planning: The Iowa Approach and Experience
It is important for states and local governments to devise and implement strategies for dealing with their water resource needs during a drought. This paper discusses the mechanisms that...
Formulating a Coastal Plain Water Quality Project
In 1988, the Soil Conservation Service in Delaware helped local sponsors prepare a detailed preauthorization planning report for water quality improvement in Indian River Bay watershed,...
Managing Water Table Management Systems for Water Quality
The purpose of this paper is to briefly summarize the results of water quality studies related to water table management conducted in North Carolina over the past 15 years. Results of...
Development and Application of a Model for Urban Use of Reclaimed Water
Water for nonpotable uses can be obtained from lesser-quality sources, and reclaimed water represents a very valuable and relatively unusual source. The planning and design process for...
Determination of Optimal Capacity for Water Imports
Determination of the optimal size of water import facilities is inextricably related to the issue of establishing the optimal water price, and is made more difficult by the stochastic...
Mathematical Modeling of Water Balance in a Well Defined Pilot Area
This study developed a water balancing computer code, a type of book keeping method using a detailed version of the hydrologic balance equation. The purpose was to provide a method of...
Locating and Sizing Air Release Valves on Irrigation Systems
This writing is directed to persons involved in irrigation systems and describes the usage of air release and vacuum valves. Principles described are applicable to many other piping systems,...
Water Allocation in the Bay/Delta (California)
The California Water Resources Control Board is conducting hearings, over the period July, 1987 to 1991, to review beneficial uses of the water tributary to, within, and exported from...
International Water Problem on the Rio Grande
Under a 1906 Convention between the Governments of the United States and Mexico, and under the jurisdiction of the International Boundary and Water Commission (IBWC) Mexico receives annually...
Using Role Analysis for Instream Flow Negotiations
Improved understanding of multi-agency decisionmaking has been called for but is rarely achieved, partially because there is no well known, broadly accepted technique for conducting an...
Integrated Water Use Management
Recognizing the increasing frequency of water supply problems, and the fact that many of them cannot be solved solely within county or other political boundaries, an integrated water management...
Advisory System for South Florida Water Management
A comprehensive, real-time advisory system was developed for the operation of water control facilities within the South Florida Water Management District. The Operations Assistant and...
Computer Control of Water Systems: Practical Considerations
Presented are some applications projects and procedures concerned with modeling and control of water supply and distribution systems. The work has resulted in the development of a suite...
Dynamic Modeling and Control Optimization in An Urban Area?A Case Study
